- Kube-scheduler deprecated all non-csi volumelimit plugins and removed those from defaults plugins. 
  - AzureDiskLimits
  - CinderLimits
  - EBSLimits
  - GCEPDLimits
  
  The NodeVolumeLimits plugin can handle the same functionality as the above plugins since the above volume types are migrated to CSI.
  Please remove those plugins and replace them with the NodeVolumeLimits plugin if you explicitly use those plugins in the scheduler config.

- Fixed a regression since 1.24 in the scheduling framework when overriding MultiPoint plugins (e.g. default plugins).

- Scheduler no longer runs the plugin's `Filter` method when its `PreFilter` method returned a Skip status.
  In other words, your `PreFilter`/`Filter` plugin can return a Skip status in `PreFilter` if the plugin does nothing in Filter for that Pod.
  Scheduler skips `NodeAffinity` Filter plugin when `NodeAffinity` Filter plugin has nothing to do with a Pod.

- [migration phase 1] PodFitsHostPorts as filter plugin ([#83659](https://github.com/kubernetes/kubernetes/pull/83659), [@wgliang](https://github.com/wgliang))
- [migration phase 1] PodFitsResources as framework plugin ([#83650](https://github.com/kubernetes/kubernetes/pull/83650), [@wgliang](https://github.com/wgliang))

- Scheduler skips NodeAffinity Score plugin when NodeAffinity Score plugin has nothing to do with a Pod.

- Kube-scheduler: a plugin enabled in a v1beta2 configuration file takes precedence over the default configuration for that plugin. This simplifies enabling default plugins with custom configuration without needing to explicitly disable those default plugins.

- Scheduler framework permit plugins now run at the end of the scheduling cycle, after reserve plugins. Waiting on permit will remain in the beginning of the binding cycle.

* kube-apiserver: the `Priority` admission plugin is now enabled by default when using `--enable-admission-plugins`. If using `--admission-control` to fully specify the set of admission plugins, the `Priority` admission plugin should be added if using the `PodPriority` feature, which is enabled by default in 1.11. ([#65739](https://github.com/kubernetes/kubernetes/pull/65739), [@lig...

* Added support to a hierarchy of kubectl plugins (a tree of plugins as children of other plugins). ([#45981](https://github.com/kubernetes/kubernetes/pull/45981), [@fabianofranz](https://github.com/fabianofranz))
    * Added exported env vars to kubectl plugins so that plugin developers have access to global flags, namespace, the plugin descriptor and the full path to the caller binary.
